In this episode the boys are focussed on a hoard of 1400 Roman bronze coins unearthed near Turvey, Bedfordshire in December 2006. The coins date from the middle of the 4th century towards the end of the Roman Empire in Britain. Some coins in the hoard have a propaganda message stamped across them: ‘happy days are here again’; others are emblazoned with the names of two Roman usurpers Agnentius and Decentius. Gary and Gordon are keen to return to the site with their state-of-the-art technology in the hope of finding missed coins; Gordon even believes there’s an opportunity to find a whole new hoard.
